I've always liked the look of factory buckets so I decided to gut the bench seat interior in favor of bucket seats. After no luck trying to track down a decent set of 1970 buckets seats $$$$, I decided to go another route by using my old 1970 bench seat brackets for the drivers seat and some old beat up bucket seats from a 73 and up truck which are cheaper and easier to find. I was pretty happy with the results.

Before & After 1970 C10

Here's what I started with:

I found a local guy who had around 10 of these 73 and up seats lying around.
Pretty sure they were out of a 1975 truck. Once the brown seat had the nasty cover off there was the little chrome square in the center.

Here is the key to making bench seat brackets work on the drivers side bucket seat. 2 simple easy to make brackets

Here's what the seat frames looked liked after tear down. I doubt GM painted these back in the day judging by the amount of rust that came off of mine. I had to get new back rest springs, they had completely rusted and broke.

and after being sandblasted and powder coated, mocked up in the truck:

The passenger side seat brackets I just ordered from ECE (Early Classic Enterprises) They are direct bolt in.

Now for the driver' side. As you can see from the pic, the original 1970 bench seat brackets both required some light modification in order to work with the new bracket adaptors. The rear mounts were shortened and flipped "forward" and welded in place. Just use the original bench seat floor bolt holes for the driver's side seat bracket (one closest to the door) New floor holes will have to be drilled for the other bracket (closest to the console).

This what the bracket adaptors look like once bolted to the drivers seat:

I had to mess around to get the right height that's what the wood blocks are for and notched the rear bench seat bracket mounts for clearance issues. I also drilled a new bolt hole on the bench seat bracket mount closest to the center console, again for clearance issues.

and what it looks like once everything is bolted in place. 5/16 holes were drilled and tapped into the bracket adaptors:Attachment 1276817

For my seat foam I contacted a board member Tim aka "Truckseats" awesome guy to deal with. Good' ol made in the USA seat foam:

I should have got my Truckworld seat covers from Truckseats as well but I made the mistake of going with Classic Parts of America. They assured me that they were sending Truckworld covers but they sent me PUI covers instead . Anyways after they tried to deny it I provided them a transcript of the conversation I had with the salesman when I ordered them online. So they finally agreed to take them back and send me the correct Truckworld seats covers. It took 4 months all said to finally get them but it was worth it. It also allowed me to compare both the PUI cover and Truckworld covers. Glad I held out.

As far as I can tell the scrolling on the Truckworld seat cover is more crisp and they use more stitching where needed.

can you tell me how and where you decided to drill your holes in the floor to go from bench to buckets? did u use the existing holes on the outside and then drill where the other ones would go?

It wasn't bad at all. I just used the existing driver's side bench seat bracket holes. I had to drill 4 new holes for the drivers side bracket closest to the console. It was easy enough with the other bracket to reference from.
For the passenger side just a little correction, it was not direct bolt in. 3 new holes had to be drilled. Only the existing outside front could be used.

Hey no worries special K, thought I'd give back a little since this site has helped me out so much already with my truck. Paying $200 for 2 used buckets and 2 consoles was a lot cheaper than the $600 + for used factory originals I was coming across.
